LIQUID-VENDING AIPAMTUS.

To all whom it may concern:

Be it known that I, JACOB ZILL a citizen of the United States, residingat liialtimore, in the State of Maryland, have invented certain new anduseful Improvements in Liquid-Vending Apparatus, of which the followingis a specification.

This invention relates to an improved apparatus for vending liquids andhas for one of its objects to provide a novel construction andcombination of elements whereby liquids in a predetermined quantity maybe delivered through theaction of a coin and the manual manipulation ofa -coin-carrier.

Another object of the invention is to provide an improved constructionof device which may be readilyleonnected to any source of liquid-supplyorifstorage receptacle so that the liquid may fiflow-either, under Vpressure or by gravity anddi-spense the. liquid therefrom.

With these and other '0 drawings, in which,-

Figure 1, is a perspective view of the apparatus, Fig. 2, a verticallongitudinalcrosssection thereof,the section 'eingtaken on the line 22of Fig. 3. Fig. -3,i sl ahorizon-Y ated the upper valve to fill themeasuring chamber and is about to actuate the lower valve mechanism todischarge the measured liquid. Fig. 7, is a cross-sectional view throughthe coin-carrier,-the section being taken on the line 77 of Fig. 3, andFig. -8, is a sectional detail of the upper part of the measuringchamber and the valveto control the admission of liquid thereto-Referring to the drawings the numeral, 1, designates a case of anysuitable form or construction having a bottom, 2; a top, 3; front andrear-walls, 4, and, 5, and side walls, 6, and, 7.. Onithe inside of thecase and 1n the present instance located in the corner formed by thebottom, 2, rear wall, 5, and side wall, 7 provide a receptacle, 8,

a valve chamber, 9, with asli htly inclined bottom, 10, therein. At theower end of this inclined-bottom I enter a discharge tube, 11, whichextends through the front wall, 4, of the case and has a down-turnedouter end, 12, which forms a discharge nozzle.

A measuring receptacle, 13, extends vertically above the receptacle, 8,and said measuring receptacle is provided with a vertical chamber withan outlet port, 14, at the bottom thereofwhich may be made tocommunicate with the valve chamber, 9. suitable valve, 15, is sustainedin the valvechamber so as to cover or uncover the port, 14. This valvemay be operated in various ways but in the present instance it ismounted on a lever, 16, having one end, 17,

presently be described. The upper portien {of the measuring receptacleis circular 1n cross-section and extends through the top wall, 3, of thecase, as clearly shown in Fig.

4 01 the drawing and the upper projecting endithereof is provided withclrcumferential screw-threads and has a circular flange, 19

which rests upon said top. A valve-seat, 20, is formed at the uppercylindric. end of the measuring receptacle and a'valve, '21, controlsthe admission of liquid thereto. In the present instance this valve iscarried by two vertical rods, 22, which extend vertically through theflanged cylindric end of the measuring receptacle and have their lowerends connected to a yoke, 23, which is curved to conform to the exteriorshape of the receptacle so that the two rods may have positiondiametrically opposite eachv other.

A cylindrical shell, 24, has a screwthreaded lower inner end which fitsover the upper end of the measuring receptacle and forms a chamber, 25,about the admission valve, 21, and a liquid-supply plilpe, 26, en-

she

but in the present instance'it is rigidly se- I cured to the rear wall,5, by means ofa dove-tailed block, 27, and to the side wall, 7, througha horizontal bar, 23, having at its bottom a dowuwardly-projectingflange, 29, that enters a groove, 30, in the receptacle.

In operation the upper and lower valves of the measuring receptacle areactuated in succession,--that is the upper valve, 21, is raised topermit the liquid to run into and fill the measuring chamber and thesaid valve is then. closed so as to momentarily confine the liquid inthe'said chamber between the two valves. The lower valve, 15, is thenopened and the measured contents will then run out through port, 14,valve chamber, 9, and pipe, 11, to discharge nozzle. As the .valve, 21,is the first to be operated the mechanism employed for that purpose willfirst be described.

A lever, 31, has one end pivotally sustained adjacent the side wall, 6,of the case and said lever normally inclines downwardly from its pivotedend. The free end, 32, of this lever has position at the side of themeasuring receptacle and said end is pivotally connected with the lowerend of the rod,

33, whose upper end engages the yoke, 23. It will therefore be seen thatby raising the free end of the lever, 31, the rod, 33, Will be elevatedand as the yoke, 23, is eonnectedto the said rod it will be raisedcarrying the valve rods, 22, and valve, 21, with it. By reference toFig. 3, it will be seen that in the present instance the lever, 31, ispivotally mounted by means of a horizontal rod, 34, from which itprojects, and which has bearing in the front and rear walls, 4, and 5,so that it may rock. This rod, 34, is provided with a central tongue,35, which inclines downwardly at a point directly over that where thecoin enters the machine and is to be operated thereby as will now beexplained.

On the interior of the ease and extending horizontally therein betweenthe walls, 6, and, 7, are two spaced-apart guide rails or bars, 36.These guide-rails each have a tongue, 37, at their inner vertical sidesso as to sustain and guide a horizontal coin-carrier or slide, 38. Thisslide projects through an opening in the side wall, 6, of the case andhas position directly beneath the downwardly inclined tongue, 35, on therod, 34. The inner end of the slide has a groove, 39, in its uppersurface which is of sufiicient width of receive the coin, 40, edgewise;this groove is open at its innermost end to allow the coin to pass off.Lugs or stops, 41, project upwardly from the inner end of thecoin-carrier and prevent the entire withdrawal of the same from the caseby contacting with the'inner vertical side of the wall, 6, as clearlyseen in Fig..2. A pin, 42, projects rearwardly from the inner end of thecoin-carrier and a tube, 43, is carried by the wall, 7, and in directline with the pin so as to receive the latter when the coin-carrier ispushed inwardly. A coiled spring, 44-,

has one end entering the tube, 43, and its other end coiled about thepin of the coincarrier, and said spring normally keeps the coin-carrierpressed outwardly and in the position shown in Fig. 2. A coiled spring,45, is also provided to keep the inner end of the lever, 31, pressed ordrawn downwardly.

The coin, 40, is placed in the groove, 39, of the slidable coin-carrierand the depth of the groove is such that the coin while standing on itsedge in an upright position will project above the upper surface of thecarrier, as shown in Fi s. 2 and 6. A slot, 56, is provided in the sideWall, 6, so the coin may pass into the case while remaining on edge inthe groove. After the coin has been inserted in the groove of thecarrier the latter will then be pushed inwardly so that the upperprojecting edge of the coin will contact with the bottom side of thecentral tongue, 35, and raise the free end of said lever, 31, togetherwith the rod, 33, and thereby elevate yoke,23, rods, 22, and inletvalve, 21, to permit the liquid to enter the measuring chamber. Thisupward movement of the lever, 31, and connecting valveparts continuesuntil the coin, 40, passes beyond the central tongue, 35, whereupon thelever and said valve parts will immediately drop and shut off the supplyat the upper end of the measuring receptacle. This opening and closingof the filling valve, it will thus 'be seen, is effected by what may betermed the preliminary movement of the coin-carrier and effects ameasuring of the liquid that is to be discharged upon the final movementof the coin-carrier as will now be described.

A discharge-valve lever, 46, is pivotally mounted between its end at, 47and extends longitudinally above the inner end of the coin-carrier. Theforward end, 48, of this lever has position over the coin groove, 39,and coin, 40,'at the time the tongue, 35, drops behind the coin to closethe filling valve so that as the coin is carried forward by the furthermovement of the carrier, it will contact with the lower side of thelever, 46, and raise said end. The rear end, 49, of this lever projectsbeyond the pivot, 47

and is swung downwardly as the forward drawn from beneath it so the coinwill then drop down onto the bottom of the case. A spring, 50, operatesat the forward end of the lever, 46, to depress said end and close thedischarge valve, 15. It will thus be seen that normally both valves, 15,and, 21, are closed at the two ends of the measuring receptacle; thatthe filling valve, 21, is first opened to let the liquid flow into andfill the measuring device and immediately closes; and finally the lowervalve, 15, is opened to allow the measured liquid to run 011?, and thatall of these operations are effected by the preliminary and final inwardmovement of the coin-carrier and coin.

Having thus described my invention what I claim and desire to secure byLetters Patent is, 1. In a liquid vending apparatus the combination witha case, of a vertical lneasurin receptacle having an inlet at its upperen and an outlet at its lower end; a liquid supply at the upper end ofthe measuring re ceptacle; a valve movable vertically with respect tosaid inlet to control communication between the supply and the inlet tosaid receptacle; rods connected to and depending from said valve; alever pivotally having an inclined bot-tom and forming a 1 chamber; adischarge tube communicating with said chamber; a valve in said chamber;means for operating said valve; a measuring receptacle extendingvertically above said valve; a valve at the upper end of said measuringreceptacle; rods connected to said latter valve and depending at theside of the measuring receptacle; a yoke connected with said rods; alever for operating said yoke to move it vertically with respect to themeasuring receptacle, and a connection between the yoke and said lever.

3.' In a liquid vendin apparatus the combination with a case, of achambered receptacle in said case; a valve pivotally sustained in saidchamber; a measuring receptacle extending vertically above said chamberand having its lower end closed by said valve; a lever pivoted at oneside of the measuring receptacle and connected with the valve in the.chambered receptacle; a shell around the upper end of the measuringreceptacle: a valve in said shell; means for operating said latter valveto control communication between the shell and the measuring receptacleand a supply pipe entering said shell.

. In testimony whereof I afiix my signature in presence of twowitnesses.
